Suppose you and your husband have decided that when you retire in 15 years you want to take a trip around the world for a year. You realize that you need to begin saving now for this trip of a lifetime. You want to be able to deposit annually (end of year payments) a fixed amount in an interest bearing account. It is estimated that monthly after that you will need to withdraw $5000 monthly for spending money. You will make the down payment at year 15 and the monthly payments will begin the first month after year 15 and will go for 12 months. How much must you deposit annually to be able to pay for these expenses. Assume 6% interest annual rate with monthly compounding.
